Caption: Figure 5.
Top panels: best fit to the IXPE, XMM-Newton, and NuSTAR data and corresponding residuals. On the left, the model tbabs × const × polconst × po fitting the I Stokes spectra is shown, while the right panel displays the best-fit Q and U Stokes spectra. Bottom panel: confidence regions corresponding to 68%, 90%, and 99% uncertainties derived using the full IXPE 2–8 keV data.
